Question

我使用自制软件来安装GCC 4.7.0，而我的项目的make在汇编时失败了。我可以成功地从.c - ＆gt;中获取代码。 .s，但.s - ＆gt; .o失败。

要查看用于安装GCC的brew配方，请查看：https://github.com/Homebrew/homebrew-dupes/blob/master/gcc.rb。我还使用https://github.com/mxcl/homebrew/blob/master/Library/Formula/binutils.rb从上游安装了binutils。安装binutils似乎没有在/ usr / local / lib或类似的地方引入新的“as”。

如何追踪这个缺失的指令错误？看起来编译器是正确的，但链接器根本不支持这些指令。说明似乎是矢量指令。

当我使用MacPorts安装的GCC-4.7（它使用cctools）时会出现这种情况。我尝试更改优化，看看是否也有帮助。

Answer 1

将-Wa,-q添加到编译器标志为我解决了这个问题。从手册页中可以看出：

-q

使用clang（1）集成汇编程序代替基于GNU的系统汇编程序。

-Wa部分将它从编译器驱动程序传递给汇编程序，就像-Wl将参数传递给链接器一样。

Answer 2

简短的解决方案是删除'-march = native'选项（至少它对我有用）。

Answer 3

您似乎正在运行不了解AVX扩展程序的as版本。您需要构建较新的gas或使用clang进行汇总。

在Mac OS X上组装项目时出错“没有这样的指令”
